My road king leaks motor oil if the oil is higher then half way up the hash marks,(cold). The first time it happened was after the dealer did the thousand mi service. There was a quarter size spot on the floor the next morning. when I checked it the oil was three quarters up the Hash marks (cold). the dealer put dye in the tranny then the motor ,while they where trying to figure out where it was coming from over the miles the leak stoped, approx. 1000 miles later. the oil level was back to half way. when I changed the oil at 3000 mi the same thing happened again. thousand mi later it stopped, when it got back to half. So I keep it under halfway and it doesn't leak. Is this normal, is there an over flow between the primary and the crank case (thats were the oil is coming from)or is it a seal? The dealer is saying its an over flow or breather , but I can't see one on the mtoor or in my facrory service manual.
